Construction & Design

The ARP Hex Bolt Kits are constructed from high-grade 8740 chromoly steel, known for its excellent strength-to-weight ratio and toughness. The bolts undergo a proprietary heat treatment process that enhances their tensile strength and fatigue resistance, making them suitable for high-stress environments. The black oxide coating not only provides corrosion resistance but also reduces glare and enhances the bolt's appearance.

The flanged hex head design allows for better torque application and minimizes the risk of head stripping during installation. The precise machining of the threads ensures a smooth, accurate fit, reducing the risk of cross-threading or damage. The 50mm underhead length offers flexibility for various mounting depths and configurations, making these bolts adaptable to multiple applications.

Installation & Fitment

The ARP Hex Bolt Kits are designed for straightforward, bolt-on installation. They utilize standard M10 x 1.50 metric threads and can be installed using common hand tools such as wrenches or socket sets. No special modifications, cutting, or drilling are required for most applications. Proper torque specifications should be followed to ensure optimal clamping force and safety. Always refer to your vehicle or equipment's service manual for specific torque values and installation procedures.
